Americans are being encouraged to be cautious even if they're fully vaccinated against COVID-19.
Dr. Anthony Fauci is encouraging people to stay home as data shows the virus is still transmissible from someone who has been vaccinated. Fauci also believes it's possible that Americans may still need to wear face masks going into 2022. Dr. William Schaffner of Vanderbilt University Medical Center says older Americans who have been vaccinated can relax their social distancing a little, but should still remain cautious.
